I have one of the cascade units and so I'll have a look and see if I can't see what regulator they use. It is ugly, but I was going to put in a small box as it isn't very big.
Good luck with construction and always remember, you get what you pay for
I took a look at their site and also came across another unit which costs a little more ($20), but takes a grounded IEC plug at the input and is "Fully regulated and filtered" (and 3amps for what that's worth in this application).
its the second one down on this page: http://www.hosfelt.com/en-us/dept_16.html
Also, on the same page you originally referenced: http://www.hosfelt.com/en-us/dept_9.html The first unit on the list is 2.4amps and "Regulated, Filtered and Grounded", but it still of the wall-wart configuration in that the block itself plugs into the wall. This is only $10, does the fact that its output is a little higher and that its grounded offer any advantages to the unit you originally mentioned?
Why don't you buy one of each and try them?
I should conseder self medicating again.
.... I think you were looking at the wrong power supply. The one I was referring you to was the second one down on this page:http://www.hosfelt.com/en-us/dept_16.htmlIts a 3amp'er and 5-3/8" x 3-5/16" x 2-1/2" in size... is it likely to be a linear supply?$20 is still pretty reasonable if it looks promising.
if it were 120/240 it would indicate that it has a transformer whose primary can be switched from parallel to series, indicating, typically a linear supply. But the fact that it can cope with any AC voltage from 100-250V, clearly indicates its a switcher having no input transformer. Honest.See, snarky, yet edumicational
How did things work out with the supply you ordered? Was it the Hosfelt7202c-3? Correct connector for the SB@?
